RAIL-ANCHOR.

Specification of Letters Patent.

Patented Feb. 15, 19211.

To all whom it may concern:

Be it known that I, HAROLD G. WARE, a citizen of the United States,residing at Park Ridge, in the county of 'Cook and 5 State of Illinois,have invented certain new and useful Improvements in Rail-Anchors, ofwhich the following is a specification.

My invention relates to devices for pre venting the longitudinalcreeping movement commonly called anticreepers, rail stays or railanchors.

The principal object of this invention is I to improve upon the type ofrail anchor disclosed in the patent to D. F. and D. L. Vaughn, No.1,021,387, granted March 26, 1912. This type of anchor consists of ashoe member adapted to bear againsta tie and to engage one edge of thebase of the rail to which the device is applied, and a torsional springyoke which extends under the rail base, engages the shoe and theopposite edge of the rail base, and is strained, when in its operativeposition. The present invention improves upon this type of anchor byproviding a shoe member which may be more conveniently and economicallymanufactured than the malleable casting which forms the shoe member ofthe patented anchor, and one which can be made considerably lighter thanthe shoe of the patent, without the sacrificing of the necessarystrength and rigidity required in devices of this character. Theminimizing of weight in devices of this class is an importantconsideration, as rail anchors are manufactured in large quantities,sold at a relatively low rate per article, and frequently have to beshipped to points remote from the place of manufacture, so that the costof transportation is a substantial factor in the cost of the articles tothe railroad company.

The invention consists in the novel arrangements, constructions, andcombination of parts, hereinafter described and claimed for carrying outthe above stated objects, and such other objects as may appear from thefollowing description.

The invention is illustrated in the accompanying drawings, wherein-Figure 1 is a plan view of a rail anchor constructed in accordance withmy invention, and shown applied to a rail;

the spring yoke member of the anchor before being applied to the rail;

Fig. 9 is a view illustrating the form of blanks from which shoe membersof the above type are formed.

Like characters of reference designate like parts in the several figuresof the drawings.

Referrin to the drawings, 25 indicates a railroad rail, and 26 one ofthe cross ties on which the rail is supported. The rail anchor, asillustrated in the drawings, consists of a shoe '27 and a spring yoke28. The yoke is the usual form of spring yoke now used in connectionwith the Vaughn anchor patented in the patent above referred to. It ismade'from a flat piece of steel which is given a torsional set and isformed at one end with a notch 29 to engage one edge of the rail baseand at the other with an upstanding lug 30 to engage the shoe member 27,the lip 31 by which the upper edge of the notch 29 is defined being bentforwardly toward the tie (having reference to the position ofapplication of the anchor to the rail) as shown in Fig. 1.

The shoe is formed of sheet metal which is cut from a blank having thecontour indicated in Fig. 5. The blank, after being cut to this shape,is bent along the lines a, I), c, to provide a rail base engaging jawformed of an upper lip 32 and a lower lip 33, the latter of whichpreferably lies horizontally under the rail base, a tie abutting flange34:, and a connecting web 35. The blank is out so that a notch 36 isprovided between the rear edge 37 of the connecting web and the forwardedge 38 of the lip 33. This notch is designed to receive the lug end. ofthe spring yoke and is preferably slightly wider than the thickness ofthe material from which the spring yoke is formed. The lower edge of thespring yoke 18 thinned edge 38 of the lip 33. The width of the i down toprovide a shoulder 39. This shoulder engages a projection 40 which isformed on the edge 37 of the connecting web 35. Preferably the portionof the anchor designated 41, which connects the upper lip .32 and thelower lip 33, and the connecting web 35, is pressed out to form a boss42. The purpose of this is to increase the width of the shoe at thisplace so that shoes so formed may be used interchangeably with themalleable iron shoe, heretofore employed in anchors of this type,without change of the dimensions of the spring yokes.

To apply the device to the'rail, the shoe member is fitted over one edgeof the rail base with its tie-abutting flange bearing against the tie.The yoke member'is hooked over the other edge of the rail base, and isbent, was to straighten out its torsional set sufliciently to permit theend of the yoke having lug 30 to be raised into notch 36 in the shoe,with shoulder 39 on the yoke engaging projection 40 on the shoe, and theupper edge of that portion of the spring yoke which extends under therail base in interlocking engagement with the shoe member and bearingagainst the forward notch 36 is preferably just suflicient to permit theupper edge of the yoke member to be readily inserted to its interlockingposition with clearance suflicient to permit the yoke member to assume adiagonal position across the rail base. The torsional strain to whlchthe spring yoke is subjected keeps the anchor in close engagement withthe rail. The yoke is prevented from becoming disengaged from the shoebecause of the bearing of the shoulder 39 on the lug 40 and theengagement of the upper edge of the yoke with the forward edge 38 of thelip 33.

In Fi 7 to 9 inclusive I have shown a modi ed form of anchor in whichthe lower lip 33 of the shoe member 27 is tapered toward its end asindicated at 41 so as to permit the jaw end 29. of the spring yoke 28 tomove rearwardly with the rail a greater distance than is possible withthe form of lip shown in Figs. 1 to 6, inclusive, without danger ofdistorting or breaking the yoke. When the yoke 28 assumes the diagonalposition across the rail as indicated at A in Fig. 7 of the drawings,for example, during a retrograde movement of the rail when the shoemember is frozen in the ballast of the road bed or otherwise held inarelatively fixed position, the anchor device increases its grip on,therail base so as to resist further rear-ward movement of the rail.

The shoe member 27* is preferably made from" a blank 42 having aconfiguration which permits one blank to nest with another as indicatedin Fig. 9. A plurality defined on one side by of blanks of this form, itwill be noted, may be cut from one sheet of metal without anyappreciable loss of material. In other respects, the spring yoke andshoe member of the above modification may be the same as that shown anddescribed in connection with Figs. 1 to 6 inclusive of the drawings.

This application is a continuation in part of my co-pending application,Serial No. 306,342, filed June 24, 1919.
